Frequency tables

Brainstorm

Investigating frequency

Examine the following frequency tables. What information could these frequency tables be giving you? What information is missing? What other information do you need in order to determine exactly what these tables are about?

Throughout this learning activity, you can record your thoughts digitally, orally, or in print.

Data terms

Check out the following important key words and their definitions. We will be using these key words as we discuss data. Read through the terms. Which terms do you know, and which are you learning about for the first time?

Match each term to the corresponding definition.

Now examine the frequency tables from our Minds On activity. Which of the tables is showing discrete data? Which is showing continuous data? How do you know? Do you need more information?

Quantitative vs. qualitative data

Now you will create your own chart about a character, celebrity, animal, or pet of your choosing! Complete the Qualitative and Quantitative Data Chart in your notebook or using the following fillable and printable document.

Think-Pair-Share

Both qualitative and quantitative data are important and useful for different situations.

When do you think it would be beneficial to use qualitative or quantitative data? Is one type of data more useful than the other?

Record your ideas in a method of your choice and discuss your answers with a partner, if possible. Be ready to share!

Note to teachers: See your teacher guide for collaboration tools, ideas and suggestions.

Discrete or continuous?

Complete the Discrete or Continuous Data Chart in your notebook or using the following fillable and printable document. Place each description of a data set into the correct category on the chart. For each, you are deciding whether they are discrete or continuous data. You may discuss these with a partner, if possible, or record your thoughts independently.

Frequency tables

Once we have gathered our data about a given topic or question, the data is often put into a chart or a table to display the results. The steps in the following example breakdown how we examine data and organize it into a frequency table.

Frequency table example

A group of community members were surveyed and asked the following question:

How many pets do you have?

Examine the data set collected from the initial survey in the following table.

Student tips

Student tips

The following are components you should know when creating a frequency table.

  • On one side of the frequency table the categories or options are listed.
  • In the next column, the tally is recorded.
  • In the last column is the frequency for each category/option displayed as a number.

What do you notice? If you were going to create a frequency table, what elements would you want to include?

Record your thoughts in a method of your choice.
